SPRING CUSHION STRUCTURE.

Application filed March 7, 1924. Serial No. 697,442.

The invention relates to spring cushions and particularly to the structure c that type of cushions in which each spring is held 1n an individual pocket.

The various objects of my invention canbest be understood from the description which follows, and from the accompanying drawings, in which,

Fig. 1 is a combined top plan view and partial horizontal section of a cushion structure embodying my invention.

Fig. 2 is a vertical section of the same taken on the line 2-2 of Fig. 1.

Fig. 3 is a perspective view of one of the strips.. fo rmingFthe pocket as it appears in position, and ig. 4 is a front view of the same as it appears before it has been bent and seamed into position.

S ring cushions have heretofore been ma e largely in units, each unit comprising a complete row of springs entirely encased and ready for insertion into a casing, each spring bemg contained in an individual substantially cylindrical pocket. It has been found that the structure just described is wasteful of material due tothe duplication of material for covering the ends ofthe pockets. Other cushions have, therefore, been made with substantially square pockets for individual springs by seaming partitions to the top and bottom of a casing and there- 'by utilizing the casing for one or both of the ends of the pockets.

My improved structure contemplates the :use of a partly open semi cylindrical and semi-square pocket formed of short pieces of material which are usually wasted whereby I am enabled to save considerable ma: terial and am further able to use a minimum of labor in the assembly of said structure.

An outer casing as 10 has secured thereto suitable. strips as 11, substantially of the same height as the height of the completed pockets together with the seamed edges 21 and 22 thereof and of substantially less width than twice the width of the completed pocket. After the attachment to the to 14 and to the bottom 15 of said casing, 0 one of the edges as 21 and 22 respectively of each strip 11, the peripheral edges of said casing may be brought together and seamed as at 13 to form a closed structure, complete with springs as 12 suitably held therein. To stretch the casing 10 into its preferable rectangular prismatic form, wherein a top 14, a bottom 15, sides 16 and 17, andtedges 18, are formed, reliance is preferably had upon the extension of the springs 12 into contact with said top 14'and bottom 15 after said springs have been inserted into the unseamed casing, as will be more fully described hereinafter.

I prefer to bend each of said strips 11 into "a pair of walls 19 and 20 in mutually perpendicular relation, one wall as 19 bein made substantially parallel to theside 17 o the cushion structure, whilethe other wall as 20 is made substantially parallel to the edges 18 of said structure, said stri s being arranged in rows, so that the wa s 19 of one row of strips are in alignment and the walls 20 of a perpendicular row are also in alignment.

The inner faces of said walls 19 and 20 cooperate with the outer faces of the corresponding walls of adjacent partitions to form the complete pocket. Before assemon the inner surface of the top 14 and of the bottom 15 of the casing 10, lines substantially in the form of a series ofsquares bling the pocket structure, I prefer to mark indicating in which positions and at which points the partitions 11 are to be seamed;

It will be seen that each 'of said strips 11 is thereby formed into angular form with the edges 21 and 22 thereof turned preferably outwardly from the walls, and seamed as by means of the seams 23 and 24, to the top 14 and the bottom 15 of the casing, respectively.-

Each of said artitions 11 is preferably slitted inwardly rom the edges 21 and 22, a sufiicient distance, as by means of the slits.

40, each substantially perpendicular to the edges of said partition, to allow said partition to be bent readily into the perpendlcular pocket walls 19 and 20. By reason of saidslits, I am enabled to round the corners of the pocket at the juncture of the walls 19 and 20 to follow substantially the cylindrical shape of the spring 12, as will be seen from Fig. 3. This results in. a considerable saving of material. Furthermore, by reason of the divergence of the edges of the slits 40 when a convex surface as 41on the outer face of the angle at the juncture of the walls 19 and 20 is formed, I eliminate the creases and folds which would otherwise result when the partition 11 is bent at right angles to form said walls, thereby making the seamr ing of the edges 21 and 22 to the casing 10 as bymeans of the seams 23 and 24, a rapid and. simple operation requiring little t1me and effort.

It will be seen that each of'the strips 11 is positioned in the same relative position in the cushion structure so that the bend '41 thereof, as viewed in Fig. 1, is at the lower left-hand corner of each of said strips. It will also be noted that the strips 11 are entirely independent of, and'are unconnected to, each other in anyway, whereby a series 7 side 17 of the cushionv structure or to the edges 18 of said structure to reach any or all of the pockets in a row.' It will be obviousfrom the fact that no material is used at said spaces that considerable material is eliminated from the otherwise substantially square pocketwithout loss of the spring enclosing eifect of the pocket, said pocket being stitched at the top and bottom, and sai are ,brotigu I the sti 'ng 13, completing aces being made considerably less than the dlameter of a spring 12, whereby said spring cannot pass out of the pocket through said spaces. It will be understood that for the purpose of inserting the springs 12 into their respective pockets, the side 17 or'one of the edges 18 of the casing 10 may be left un-- seamed by the stitching 13 until all of said springs have been inserted into their respective pockets. 4

It will also be understood that when a suitable spring carrying tool is inserted into the pockets through the spaces25 and through the edge17 of the cushion structure, that the row of pockets to the right of said tool, .as viewed in Fig. 1 is filled by said tool, while if the tool is inserted between the rows and through the spaces 25 through the upper edge 18 (Fig. 1% that row of pockets to the left of said too s is filled. After insertion of allof the springsintothe pockets has been completed, the edges of the casin 10 t together, and readily seam by the structure, and maintaining the parts in their permanent operative relation.

Only one thickne$ of materialis provided b at all parts of each pocket of-my im roved cushion for purposes of economy, whi e-suitable spaces 25 are provided, for allowing the rapid insertion into the pockets of an entire row of springs at a time, a.s hereinbefore described. It will-be seen that any improved arrangement of the pocket form} mg partition 11 provides a pocket in which two of the walls as 19 and 20 are formed A by one partition, while the other two walls are formed by the wall 19 of one of the adjacent partitions and the wall 20 of the of short strips, usually of waste material,

and also to'the-use of the slits 40 in the partitions.

' Said partitions may-be readily and rapidly seamed to the casing by means of a single line of stitching 44 beginning at one tantially square in edge as 18 of the casing and running without interruption completely across the casing to the other edge, a second line of stitching 45 1 perpendicular to the line 44 being run from the side 17 to the sidev 16. It will, of course, be understoodthat to make .the seams 23 and 24 in continuous-lines of stitching as 44 and 45, it is advisablethat the angular strips 11 be seamed tothe'top and bottom in such a manner that the edges 21 and 22 of said angles are-turned outwardly as shown clearly in Fig. 3.-

I do not wish to limit myself to the specific structure shown herein as various changes may be made therefrom, such as for instance, in the manner of folding the edges 21 and 22, in the stitching of said edges, in the lengths and positions of the slits 40, in the insertion of-the springs into their pockets, in the degree of rounding of the corner of the tplocket, and in the size of the spaces 25,--wi out departing from the spirit of my invention.
